COPY HOLDER FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 724,982, dated April 7,1 903.

Application filed June 26,1902. Serial No. 113,309. (No model.)

To all whom it may concern.-

Be it known that I, FRANK E. WILLIAMSON, a citizen of the United States,and a resident of Glasco, Cloud county, Kansas, but temporarily residingat Washington, District of O0- lumbia, haveinventedanew and useful Copy-Holder for Type-Writers, of which the following is a specification.

My invention relates to copy-holders in which use is made of pointers orline'markers that are moved across the face of the copy; and it has forits object to produce copyholders of this character that shall beadapted to be used in connection with type-writers such as employmovable carriages and that are arranged to be operated automatically bythe movements of the type-writer carriage.

The invention consists in means whereby this and other objects areattained, as will be hereinafter set forth.

In order that myinvention may be the better understood, I have in theaccompanying drawings illustrated ,the preferred embodiment thereofwithout, however, wishing thereby to limit my invention to the preciseconstruction and arrangement of parts shown.

In such drawings, Figure 1 is a front view of a copyholder embodying myinvention, represented as being applied to a type-writer of a well-knownmake. Fig. 2 is a rear view of the holder, some of the parts being in a;different position from that represented in} Fig. 1. Fig. 3 is a detailview, enlarged, of the means forimparting motion to the pointer ormarker.

justable contact-piece. Fig. 6 is a detail perspective view of thepointer or line-marker. Fig. 7 is a top plan view of the means forimparting motion to the cord to which the pointer is attached.

In the accompanying drawings, A represents the stationary frame portionof a typewriter, which may be of any usual or preferred construction,and B the movable carriage. The copy-holder is supported adjacent to oneend of the type-writer, preferably near that end toward which thecarriage B is moved when it is intended to commence the writing of aline. The holder may be supported in any desired manner; but I prefer toconnect it directly with some of the Fig. 4 is a detail edge view of.Fig. 5 is an elevation of the ad stationary frame parts of thetype-writer, as I thereby am enabled to insure the holder having a fixedposition relative to the typewriter when it is set up for use.

The copy-holder consists of a supporting board or back 2. This may be ofany preferred size, preferably being about that of a legal-cap sheet ofpaper, and it may be formed of any suitable material, either woodormetal.

It is held in an n pright position by the brackets 3 and 4, to the outerends of which the board is hinged, as indicated at 5. This hinging ofthe board to its supporting brackets or standards permits of a limitedadjustment or change of the inclination of the board to suit theconvenience of the user. -The upper bracket or supporting-standard3 ispreferably formed of a pair of bars arranged to be clamped to parts ofthe stationary frame of the type-writer, while I prefer that the lowerbracket or standard should be made of highlyelastic wire, the ends ofwhich are formed into hooks 6, adapted to engage with suit-ablestationary parts of the type-writer. I do not wish to be limited tothese particular means for supporting the board or back 2; but they arewell adapted for use in connection with a typewriter such as illustratedand permit of theholderbeing quickly applied to or removed from thetype-writer, as may be required, and

at the same time support it firmly when. in use.

11 designates a pointer or line-marker in front of the board 2 andarranged to be moved across the same to indicate the line being copied.It is supported by a cord or other flexible device 12, mounted upon.rollers 13 and 14, supported at the edge of the board and preferablynear the top and bottom thereof, respectively. In order to move thecord,

and through it the pointer or marker, I carry the cord one or more timesaround a pulley or roller 15, which is arranged intermediate the rollers13 and 14 and preferably on the back side of the holder. The pulley 15is formed with or has attached to it a ratchetwheel 16, with which thereis adapted to engage a pawl 17, carried bya lever 18. The lever ispreferablypivoted in the same frame that supports the pulley 15 and uponthe same axis. It extends beyond the inner edge of the board 2 towardthe type-writing ma chine and is so disposed that when the carriage ofthe type-writer is moved to the righthand positionthat is, the positionto begin a new lineeither some part of the typewriter itself or anattachment secured thereto engages with the lever and moves it backwardinto the position indicated in Fig. 1. As the lever moves from thenormal position, (indicated in Fig. 2,) where it is held by asupporting-piece 19,.to the forward position (indicatedin Fig. 1) thepawl 17 engages with the ratchet-wheel l6 and moves the cord, and withthat the pointer.

The support 19 is so disposed as to hold the lever 18 at the properinclined position to cause it to move in advance of the carriage whenthe latter or the contact part which it may carry comes into engagementtherewith as it comes to its initial position. As the type-writercarriage moves in the other direction it gradually leaves the lever,which comes back to normal position by gravity.

Instead of having some portion of the typewriter carriage engagedirectly with the lever 18 I prefer to mount a contact-piece upon thecarriage and to make this contact-piece adjustable, so that it will givea longer or shorter movement to the lever-arm 18, according to theposition to which the contact-piece may be set.

20 indicates a holder which is arranged to be clamped to some suitablepart of the movable type-writer carriage, such as to one of the endrails thereof. In this holder there is mounted the adj nstablecontact-piece proper, which is designated 21 and consists of a plate orbar adapted to slide into and out of the holder 20.- One of its faces isratcheted, and with such face there engages a spring pawl or dog 22. Theratchet-teeth 23 on the contact-piece 21 are preferably so constructedas to allow the latter to be freely pulled out, but to prevent its beingmoved in the opposite direction except when the spring-pawl ispositively moved to free the contact-piece. It will be understoodwithout further explanation that when the contact-piece is pulled out itwill give to the lever 18 a longer movement than when it is furtherpushed into the holder and that the extent to which the pointer moves ateach reciprocation of the type-writer carriage depends upon the amountof movement imparted to the lever 18. By these means the operator isrelieved of the necessity of adjusting the pointer by hand, it beingmoved automatically a step at a time as the carriage is shifted in theusual work of typewriting. By adjusting the contact-piece in its holder20 the operator can easily cause the pointer to move over the face ofthe copy at a speed which is approximately exactly that at which he iscopying. If it should be found that the pointer is not moving at theproper speed to suit the work being done, but, as will often be thecase, it moves temporarily too fast and then temporarily too slow, theseslight inaccuracies can be easily corrected by adjusting the pointer byhand and again start- .ate itshould be normallybroken.

ing it at the proper point. In order to allow of this adjustment by handeither forward or backward, I prefer that the connection between thecord 12 and the means which actu- Thus when the lever 18 occupies itsnormal position (indicated in Figs. 2 and 3) the pawl is held out ofengagement with the ratchet-wheel 16, so that the line-marker and thecord which operates it maybe moved freely either backward or forward,such movement causing the rotation of the wheel 15 and notbeing in anywise interfered with by the pawl and its carrying-lever. This I effectby arranging a stop 25 in the path of the pawl and in such a positionrelative thereto that the nose or engaging end of the pawl is heldupward and out of engagement with the ratchet-teeth when the lever 18occupies its normal position. As soon as the lever begins to moveforward the pawl is carried out of engagement with this stop and thenfalls by gravity directly in engagement with the ratchet-wheel 16.

In order to hold the pointer down upon the copy, I provide its heelend-that is, the end which is connected with the cord 12-with acontact-piece adapted to bear against the adjacent edge of the board 2.This contactpiece may be formed of wire and made elastic. It isindicated in the drawings at 24.
